You mention you've used dietary changes in your work (OI being oral infections I presume). Do oral infections (like thrush) act as indicators about the gut biome or can one have thrush and a healthy gut at the same time?

Would that be liters of probiotic yogourt? Reduction of sugar intake? If a person's diet is generally quite good, well balanced, full of nutrients and anti-oxidants with fibre, not over-heavy in carbs or protein or fat, are there dietary changes that help?

(Drawing on your more general experience with infectious diseases if not specifically respiratory. I'm generally curious and this may straying a bit from the topic.)
